Charli bought 2 3/4 pounds of pears for 0.76 per pound and 2 3/4 pounds of grapes for 1.40 per pound. how much money in dollars and cents did charli pay for the pears and grapes?

Answers

Answer:

[tex]Total = \$5.94[/tex] ---- in dollars

[tex]Total = 594\ cents[/tex] ---- in cents

5 dollars 94 cents

Step-by-step explanation:

Given

Pears

[tex]Weight = 2\frac{3}{4}\ lb[/tex]

[tex]Amount = \$0.76[/tex] per pound

Grapes

[tex]Weight = 2\frac{3}{4}\ lb[/tex]

[tex]Amount = \$1.40[/tex] per pound

Required

Determine the amount paid for the fruit in dollar and cents

First, we need to calculate the amount paid for each fruit.

This is calculated by multiplying the amount per pound by the number of pounds bought.

For Pears:

[tex]Total_{Pears} = 2\frac{3}{4} * \$0.76[/tex]

Convert fraction to decimal

[tex]Total_{Pears} = 2.75 * \$0.76[/tex]

[tex]Total_{Pears} = \$2.09[/tex]

For Grapes

[tex]Total_{Grapes} = 2\frac{3}{4} * \$1.40[/tex]

Convert fraction to decimal

[tex]Total_{Grapes} = 2.75 * \$1.40[/tex]

[tex]Total_{Grapes} = \$3.85[/tex]

Next, we add both amounts together to get the total amount spent in dollars.

[tex]Total = Total_{Pears} + Total_{Grapes}[/tex]

[tex]Total = \$2.09 + \$3.85[/tex]

[tex]Total = \$5.94[/tex]

Multiply by 100 to convert this amount to cents

[tex]Total = 5.94 * 100\ cents[/tex]

[tex]Total = 594\ cents[/tex]

And it can be represented as dollars and cents as:

5 dollars 94 cents

A recipe calls for 2/3 cups of sugar. I have 5 1/2 cups of sugar. How many batches can I make, assuming I have a large quantity of all other ingredients?

Answers

Answer:

8.25 batches.

(Or, if rounding to the lowest amount of batches, 8 batches)

Step-by-step explanation:

We have in total 5 1/2 cups of sugar.

And the recipe calls for 2/3 cups of sugar.

So, to find out how many batches we can make, we can divide the amount of have by the amount needed. So:

[tex]5\frac{1}{2}\div\frac{2}{3}[/tex]

Let's convert the first fraction to improper form. We have 5 1/2. So, in improper form, it will be (5(2)+1)/2 or 11/2.

Therefore:

[tex]=\frac{11}{2}\div\frac{2}{3}[/tex]

To divide fractions, we keep, change, and flip. Therefore:

[tex]=\frac{11}{2}\times\frac{3}{2}[/tex]

Multiply straight across:

[tex]=\frac{33}{4}=8.25[/tex]

So, we can make 8.25 batches.

Or, we can make 8 full batches.

We have the two functions:

[tex]f(x)=-4x+3\text{ and } g(x)=3x^2+2x-4[/tex]

And we want to find (f+g)(x).

Note that this is the same thing to f(x)+g(x). Therefore:

[tex]\begin{aligned} (f+g)(x)&=f(x)+g(x) \\ &=(-4x+3)+(3x^2+2x-4) \end{aligned}[/tex]

We simply substituted them for their equations.

Add:

Hence, our answer is A.

Let b be the number of pounds of blueberries and a be the number of pounds of apples Eva picked. Which of the following expressions could represent how much Eva pays?
I'm just curious

Answers

Answer:

The required expression is: [tex]y = 5 + 2.50b + 2a[/tex]

Step-by-step explanation:

Given

[tex]Entry = \$5[/tex]

[tex]Blueberry = \$2.50[/tex]

[tex]Apple = \$2[/tex]

Required

Write an expression for this scenario

If 1 pound of blueberry cost $2.50

then b pounds = 2.50 * b

If 1 pound of apple cost $2

then a pounds = 2 * a

The required expression (y) is then calculated as

[tex]y = Entry\ Fee + Blueberry = Apple[/tex]

[tex]y = 5 + 2.50 * b + 2 * a[/tex]

[tex]y = 5 + 2.50b + 2a[/tex]

Hence, the required expression is: [tex]y = 5 + 2.50b + 2a[/tex]

Find the dimensions of the right circular cylinder of maximum volume that can be placed inside of a sphere of radius R.

Answers

This question is incomplete, the complete question is;

Find the dimensions of the right circular cylinder of maximum volume that can be placed inside of a sphere of radius R(10cm)

What is the maximum volume?

Answer:

a) Dimensions of the cylinder are; Radius = 8.1650 cm , Height = 11.547 cm

b) the maximum volume is 2418 cm³

Step-by-step explanation:

From the image

radius of the sphere is 10cm

radius of the cylinder is x and its height is 2y

so

The volume of cylinder  is V = πr²h = πx²(2y)

Get V as function of just one variable x² + y² = 100

x² = 100 - y²

Therefore V = π( 100-y² )(2y) = 200πy-2πy³

V will be a maximum when V' = 0

V' = 200π - 6πy² =0

y² = 200π / 6π = 100/3

y = √(100/3) = 5.7735

x² = 100 - y²

x² =100 - (100/3)

x = √(200/3)

x = 8.1650

So The maximum volume will occur when the radius is 8.1650 cm

and the height 2y is 2(5.7735) = 11.547 cm

The maximum volume is

πr²h = π(8.1650)² (11.547 )  

= 2418 cm³

Therefore the maximum volume is 2418 cm³

For f(x)=-5x+10, what is the value of x for which f(x) =35

X=-5

Answers

Answer:

x=-5. -5x+10 replace the x with -5, multiply, add ten, and you'll get f(x)= 35

Answer:

-5

Step-by-step explanation:

f(x) =35

f(x) = -5x +10

equate the two equations:

-5x +10 =35

-5x =35-10

-5x =25

x = 25/-5

x = -5

A shelf holds 12 books in a row. How many ways are there to choose five books so that no two adjacent books are chosen

Answers

Answer:

792 ways

Step-by-step explanation:

We can solve this using the combination formular

[tex]nCr= \frac{n!}{r!(n-r)!}[/tex] where n represents the total number of objects/items, and r represents the number of items being chosen at a time.

Hence, in this case, n =  12, r = 5, which is = [tex]nCr= \frac{12!}{5!(12-5)!}[/tex] = 792.

Therefore, there are 792 ways to choose five books so that no two adjacent books are chosen.
